Is it possible to DnD an email to the outlook plugin to create a task?
... as opposed to having to hit the add task button and then the add email as task button?
Unfortunately, you can't drag & drop emails to the Todoist plugin to add it as a task, but we may consider adding such option in the future and you're welcome to add a request for it to our Votebox: http://todoist.com/Vote/
It would be very nice feature! :-)
